<p>
        GConf has a a concept of a set of changes which can be applied or reverted
        at once: <a href="/usr/share/gtk-doc/html/gconf/gconf-gconf-changeset.html#GConfChangeSet"><span class="type">GConfChangeSet</span></a> (GConf doesn't actually apply changes atomically,
        which is one of its shortcomings).
      </p>
<p>
        Instead of a separate object to represent a change set, GSettings has a
        'delayed-apply' mode, which can be turned on for a GSettings object by
        calling <a class="link" href="GSettings.html#g-settings-delay" title="g_settings_delay ()"><code class="function">g_settings_delay()</code></a>. In this mode, changes done to the GSettings
        object are not applied - they are still visible when calling <a class="link" href="GSettings.html#g-settings-get" title="g_settings_get ()"><code class="function">g_settings_get()</code></a>
        <span class="emphasis"><em>on the same object</em></span>, but not to other GSettings instances
        or even other processes.
      </p>
<p>
        To apply the pending changes all at once (GSettings <span class="emphasis"><em>does</em></span>
        atomicity here), call <a class="link" href="GSettings.html#g-settings-apply" title="g_settings_apply ()"><code class="function">g_settings_apply()</code></a>. To revert the pending changes,
        call <a class="link" href="GSettings.html#g-settings-revert" title="g_settings_revert ()"><code class="function">g_settings_revert()</code></a> or just drop the reference to the <a class="link" href="GSettings.html" title="GSettings"><span class="type">GSettings</span></a> object.
